Patented June 14,1898.

V UNITED STATES PATENT MITOHAELH. LEVEILLE, OF WI QR OESTER, MASSACHUSETTS, ASSIGNOR OF ONE-HALF TO JOHN G. SMITH, OF SAME PLACE.

SELF-TH READING LOOM-SHUTTLE."

SPECIFICATION forming part Of Letters Patent No. 605,690, dated June 14, 1898.

Application filed November 18, 1897. Serial No. 658,942. (No model.)

To all whom/jimmy concern:

Be it known that I, M ITOHAEL H. LEVEILLE, a citizen of the United States of America, residing at Worcester, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Self- Threading Loom-Shuttles; and I do hereby declare the following to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

This invention relates to certain new and useful improvements in shuttlethreaders; and the object of my invention is to provide a simple,cheap,and eifectivemeans for threading the shuttle, such means embodying a plate or fixture which is attached to the shuttle and has a thread-guide through which the thread may be passed to the eye.

This invention is applicable to shuttles of ordinary construction, and the thread is guided from the cop over a plate, about which it passes, and from saidplate to the eye, it being retained therein by a suitable plate, which also forms a part of the fixture.

The invention also consists in the special construction of the threading attachment, as will be hereinafter fully set forth and claimed.

In the accompanying drawings, which illustrate my invention, Figure l is a plan view of a shuttle with cop in place; the threader being shown attached to the shuttle; Fig. 2 I

Fig. 3 is a side elevation is a side elevation. of the shuttle-threader detached from the shuttle. Fig. 4 is a longitudinal sectional view taken on the line a 4 of Fig.3. Fig. 5 is a longitudinal sectional view taken on the line 5 5 of Fig. 3, and Fig. 6 is a sectional view on the line 6 6 of Fig. 3.

The shuttle-body A is cut away on one side or mortised to receive the outer or side plate B of the threading'a'ttachment, which is secured in the recess or mortise by screws or in any other convenient manner, and this plate is provided with a longitudinal groove or channel b, which is similar to the channel in the side of the shuttle-body, and on a line with this groove 1) is an eye I). The plate B immediately above the eye has a recess, in which is secured a spring-plate c, which may substantially occupy the whole of the recess or be cutaway, as shown in Fig. 3, in order to secure the desired amount of spring movement, and this plate 0 is secured to one side of the kerf or slot in the plate B, through which the thread is passed. From a point adjacent to the central portion of the plate B there projects at a suitable angle a plate or thread-guide B, and its lower portion is bent upon itself, so as to provide a tubular thread guide d, which is on a line with the eye I), and the upper portion of the plate has a prong ,or projection d.

It will be noted that a slot or kerf 6 extends through the attach ment, excepting the spring, and connects with the eye and opening above the tubular thread-guide d. The threading attachment when completed is in a single piece, and the portion which projectswithin the shuttle -body is of such a length that it will be practically on a line with the end of ithe bobbin, but is positioned'at a considerable distance therefrom.

In threading a shuttle with my improvement it is only necessary to bring the thread over the prong d and draw the same toward the eye. The thread, following the kerf or slot, enters the tubular thread guide and passes beneath the spring-plate 0. After the .shuttle is threaded there is no liability of it becoming unthreaded, as the free end of the -f spring lies over the slot or. kerf.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

. 1. A shuttle-threader comprising an outer plate, which is adapted to be attached to the side of a shuttle-body, said plate having a projecting portion embodying a guide-plate and a tubular thread-guide, the outer plate and tubular thread-guide having a thread-receiving slot or kerf.

2. In a shuttle-threader, the combination with a shuttle-body,of an outerplate attached to the side thereof, and having an angular projecting guide-plate with a tubular threadguide at the base thereof, the outer plate and.

tubular thread-guide having a kerf or slot on a line with one of the side walls of the guideplate, and a spring carried by the outer plate so as to lie over the kerf 0r slot therein, substantially as shown.

3. A shuttle-threader, comprising an outer plate having an eye, a guide-plate and a tubular thread-guide, the guide-plate being provided with a prong which projects from the upper inner end thereof, the outer plate and tubular thread -guide having a kerf or slot, substantially as shown.

4. In combination with a shuttle-body having a recess, of a shuttle-threader rigidly secured in said recess and comprising an outer plate B having an eye, a slot or kerf which extends from said eye through the plate, a
